Objective: To analyze the relationship between serum prostate-specific antigen (PSA) and body mass index (BMI) according to age in a population of ostensibly healthy Korean men.
Patients and methods: Between 2002 and 2006, data from 13,025 men who visited health promotion centers were evaluated. All men underwent anthropometric measurements and serum PSA determination. The relationship between serum PSA and BMI according to age was analyzed.
Results: The median age was 50.0 years and the median serum PSA level was 0.69 ng/ml. There was no relationship between serum PSA and BMI in the group whose BMI was <23 kg/m(2). The serum PSA showed a significant inverse relationship in those with BMI of ≥23 kg/m(2). However, this finding was only true among 40- to 59-year-old middle aged men and no such relationship between serum PSA and BMI was seen in the older groups (60-79 years of age).
Conclusion: Our study revealed serum PSA had a significant inverse relationship with BMI in overweight and obese men aged between 40 and 59 years; however, there was no relationship between serum PSA and BMI in men whose age was older than 60 years.
